Question

我正在远程计算机上运行python脚本，该脚本运行正常，但是启动后不久，我得到警告：

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-myusername'

我并不担心这个警告，因为它没有停止我的代码。

然后我尝试使用Slurm工作负载管理器通过以下命令提交相同的代码：

sbatch --wrap="python mycode.py" -N 1 --cpus-per-task=8 -o mycode.o

执行此操作时，代码不起作用，并且出现以下错误：

Traceback (most recent call last):
  File "mycode.py", line 99, in <module>
    fig=plt.figure(figsize=(20, 12), dpi = 100, facecolor='w', edgecolor='k')
  File "/home/myusername/miniconda3/lib/python3.7/site-packages/matplotlib/pyplot.py", line 539, in figure
**kwargs)
  File "/home/myusername/miniconda3/lib/python3.7/site-packages/matplotlib/backend_bases.py", line 3252, in new_figure_manager
return cls.new_figure_manager_given_figure(num, fig)
  File "/home/myusername/miniconda3/lib/python3.7/site-packages/matplotlib/backends/_backend_tk.py", line 946, in new_figure_manager_given_figure
window = tk.Tk(className="matplotlib")
  File "/home/myusername/miniconda3/lib/python3.7/tkinter/__init__.py", line 2023, in __init__
self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)_tkinter.TclError: couldn't connect to display "localhost:36.0"

很明显，该错误与我生成的图形有关。我不确定它是否与XDG_RUNTIME_DIR警告有关。

任何帮助将不胜感激。

我认为您的问题与以下线程有关

tkinter.TclError: couldn't connect to display "localhost:18.0"

解决方案，如下所示更改导入

import matplotlib
matplotlib.use('pdf')
import matplotlib.pyplot as plt

更多线程

Pyplot "cannot connect to X server localhost:10.0" despite ioff() and matplotlib.use('Agg')

仅在Slurm中提交python作业时出错
